Question

If a wave has a wavelength of 9 meters and a period of 0.006, what is the velocity of the wave?

Answer 1

Divide 9 by 0.006 you should get 1500

Answer 2

Answer : Velocity of the wave, v = 1500 m/s.

Explanation :

It is given that,

Wavelength of a wave,  $\lambda=9\ m$

Time period of wave, $T=0.006\ s$

We know that the relation between the velocity, the frequency and the wavelength is given by :

$v=\nu\times \lambda$

$\because\ \nu=\dfrac{1}{T}$

$v=\dfrac{\lambda}{T}$

$v=\dfrac{9\ m}{0.006\ s}$

$v=1500\ m/s$

Hence, this is the required solution.
